Power supply and bus

communication

DD/CFF

VEGAFLEX 65 is a level sensor with pipe probe for continuous level
measurement.

It is designed for industrial use in all areas of process technology and
can be used in liquids.

High frequency microwave pulses are guided along a steel rope or a
rod. Upon reaching the product surface, the microwave pulses are
reflected. The running time is evaluated by the instrument and
outputted as distance.

Power is supplied via the H1 Fieldbus. A two-wire cable according to
Fieldbus specification serves as carrier of both power and digital data
for multiple sensors. This cable can be operated in two versions:

l via an H1 interface card in the control system and additional power

supply

l via a Linking device with HSE (High speed Ethernet) and

additional power supply according to IEC 61158-2

The DD (Device Descriptions) and CFF (capability files) necessary for

planning and configuration of your FF (Foundation Fieldbus) commu­nication network are available in the download area of the VEGA
homepage

www.vega.com under "Services - Downloads - Software -
Foundation Fieldbus". The appropriate certificates are also available
there. A CD with the appropriate files and certificates can be ordered
via e-mail under [e-mail] or by phone from one of the VEGA
agencies under the order number "DRIVER.S".

The optional heating requires its own operating voltage. You can find
details in the supplementary instructions manual "Heating for indicat-

ing and adjustment module".

Welding work

Handling

Moisture

Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.

You can find the specifications in chapter "Technical data" and on the
type label.

Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).

Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.

With threaded versions, the housing must not be used to screw in the
instrument! Applying tightening forces on the housing can damage its
internal parts.

Use the hexagon for screwing in.

Use the recommended cables (see chapter "Connecting to power

supply") and tighten the cable gland.

You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

Measuring range

Pressure

Mounting position

The reference plane for the measuring range of the sensors is the seal
surface of the thread.

Keep in mind that a min. distance must be maintained below the
reference plane and possibly also at the end of the probe ­measurement in these areas is not possible. These min. distances are
listed in chapter "Technical data" in the "Supplement". Keep in mind
for the adjustment that the default setting for the measuring range
refers to water.

The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.

The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.

4.2 Instructions for installation

Mount VEGAFLEX 65 in such a way that the probe does not touch any
installations or the vessel wall during installation.

31848-EN-120329

VEGAFLEX 65 • Foundation Fieldbus 11

4 Mounting

In vessels with conical bottom it can be advantageous to mount the

sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.

Fig. 3: Vessel with conical bottom

Inflowing medium

Make sure that the probe is not subjected to strong lateral forces.
Mount VEGAFLEX 65 at a position in the vessel where no

disturbances, e.g. from filling openings, agitators, etc., can occur.

Fig. 4: Lateral load

Extreme vibration caused by the system, e.g. due to agitators or
turbulence in the vessel from inflowing medium, can cause the coax
probe of VEGAFLEX 65 to vibrate in resonance. With coax probes of

more than 1 m (3.281 in) length, you must secure the probe by
fastening a suitable isolated brace or guy directly above the end of the
rod.

5.1 Preparing the connection

Safety instructions

Voltage supply

Connection cable

Cable gland ½ NPT

Always keep in mind the following safety instructions:

l Connect only in the complete absence of line voltage
l If overvoltage surges are expected, overvoltage arresters should

be installed according to Foundation Fieldbus specification

Tip:

We recommend VEGA overvoltage arrester B63-32.

In hazardous areas you must take note of the respective regulations,

conformity and type approval certificates of the sensors and power
supply units.

The instrument requires a operating voltage of 9 … 32 V DC.
Operating voltage and the digital bus signal are carried on the same
two-wire connection cable. Power is supplied via the H1 power supply.

Connection is carried out with screened cable according to Fieldbus

specification.

Use cable with round cross-section. A cable outer diameter of 5 … 9 mm
(0.2 … 0.35 in) ensures the seal effect of the cable gland. If you are

using cable with a different diameter or cross-section, exchange the
seal or use a suitable cable gland.

Make sure that the entire installation is carried out according to the
Fieldbus specification. In particular, make sure that the bus is

terminated with suitable terminating resistors.

On the instrument with cable entry ½ NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.

Caution:

No grease should be used when screwing the NPT cable gland or
steel tube into the threaded insert. Standard grease can contain
additives that corrode the connection between threaded insert and
housing. This would influence the stability of the connection and the
tightness of the housing.

Cable screening and
grounding

14 VEGAFLEX 65 • Foundation Fieldbus

With systems with potential equalisation, connect the cable screen

directly to ground potential at the power supply unit, in the connection
box and at the sensor. The screen in the sensor must be connected
directly to the internal ground terminal. The ground terminal outside on
the housing must be connected to the potential equalisation (low
impedance).

31848-EN-120329

5 Connecting to power supply

In systems without potential equalisation, connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor, the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen. The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). Low­frequency potential equalisation currents are thus suppressed, but the
protective effect against high frequency interference signals remains.

The total capacitance of the cable and of all capacitors must not exceed

10 nF in Ex applications.

Take note of the corresponding installation regulations for Ex

applications. In particular, make sure that no potential equalisation
currents flow over the cable screen. In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.

5.2 Connection procedure

Proceed as follows:

1 Unscrew the housing cover
2 If an indicating and adjustment module is installed, remove it by

turning it to the left.

3 Loosen compression nut of the cable entry
4 Remove approx. 10 cm (4 in) of the cable mantle, strip approx.

1 cm (0.4 in) of insulation from the ends of the individual wires
5 Insert the cable into the sensor through the cable entry
6 Lift the opening levers of the terminals with a screwdriver (see

6.4 Setup steps

Switch-on phase

Parameter adjustment

After VEGAFLEX 65 is connected to voltage supply or after voltage
recurrence, the instrument carries out a self-check for approx. 30
seconds. The following steps are carried out:

l Internal check of the electronics
l Indication of the instrument type, the firmware as well as the

sensor TAGs (sensor designation)

l Status byte goes briefly to fault value

Then the current measured value will be displayed and the
corresponding digital output signal will be outputted to the cable.

1)

As VEGAFLEX 65 is a distance measuring instrument, the distance
from the sensor to the product surface is measured. To have the real
product level displayed, an allocation of the measured distance to the
percentage height must be made. To carry out this adjustment, the
distance is entered with full and empty vessel. If these values are not
known, an adjustment with the distance values, e.g. 10 % and 90 % is
also possible. Starting point for these distance specifications is always
the seal surface of the thread or flange. With these settings, the real
level is calculated. Furthermore the operating range of the sensor is
limited from maximum to the required range.

The real product level during this adjustment is not important, because
the min./max. adjustment is always carried out without changing the
product level. These settings can be made ahead of time without the
instrument having to be installed.

In the main menu item "Basic adjustment", the individual submenu
items should be selected one after the other and provided with the
correct parameter values.

Caution:

If there is a separation of different liquids in the vessel, e.g. by
condensation, VEGAFLEX 65 will always detect the medium with the
higher dielectric figure (ε

).

r

Keep in mind that interfaces can cause faulty measurements.

If you want to measure the total height of both liquids reli ably, please

contact our service department or use an instrument specially
designed for interface measurement.

Start your parameter adjustment with the following menu items of the
basic adjustment:

Application

Each product has different reflective properties. In addition, there are
various interfering factors which have to be taken into account:
agitated product surfaces and foam generation (with liquids); dust
generation, material cones and echoes from the vessel wall (with
solids). To adapt the sensor to these different conditions, you should
first select in this menu item under "Medium" either "Liquid" or "Solid".

With coax versions, this menu item must be set to "Liquid".

Application

Liquid

Standard
(DK ≥ 2)

Measured products have different reflective properties depending on
their respective permittivity (dielectric constant). That's why there is an
additional selection option.

Under "Sensitivity" you can select "Standard (DK ≥ 2)" or "Increased
sensitivity (DK < 2)".

Through this the sensor is optimally adapted to the product and
measurement reliability, particularly in products with poor reflective
properties, is considerably increased.

Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.

Damping

Linearisation curve

To suppress fluctuations in the measured value display, e. g. caused
by an agitated product surface, a damping can be set. This time can
be between 0 and 999 seconds. Keep in mind that the reaction time of
the entire measurement will then be longer and the sensor will react to
measured value changes with a delay. In general, a period of a few
seconds is sufficient to smooth the measured value display.

Damping

0 s

Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [->] key.

A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindrical
or spherical tank - and the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed for
these vessels. They represent the correlation between the level
percentage and vessel volume. By activating the appropriate curve,
the volume percentage of the vessel is displayed correctly. If the
volume should not be displayed in percent but e.g. in l or kg, a scaling
can be also set in the menu item "Display".
